Abstract
L'invention concerne un système optique de mesure permettant de détecter des paramètres physiques et/ou chimiques d'un échantillon de liquide. Ce système de mesure comprend une source de lumière infrarouge, un porte-échantillons disposé dans le parcours des rayons de la source de lumière infrarouge et portant le liquide à examiner, un spectroscope disposé en aval du porte-échantillons et destiné à sélectionner et/ou bloquer une ou plusieurs plages de longueurs d'ondes, ainsi qu'un détecteur d'infrarouge couplé à une unité d'évaluation. Le spectroscope présente un filtre linéaire.
